Step-by-step explanation:
The UB-04 form, also known as the Uniform Bill 04, is a standard claim form used by healthcare providers to bill Medicare and Medicaid for services provided to patients. It contains various locators or fields where specific information is entered.
As for the number of unlabeled form locators on the UB-04, the correct answer is C. 4. This means that there are 4 locators on the form that are not specifically labeled, requiring the healthcare provider to enter the necessary information relevant to the claim.
It's important to fill out all the required locators accurately to ensure proper billing and reimbursement.
